Why fully working code:
document.onkeydown = function hotkeys(e) { if (!e) e = window.event; var k = e.keyCode; if (e.ctrlKey) { if (k == 77) { alert('works'); } // Ctrl + M } }
is not executed in in JSFiddle , but when run from a clean * .html document works correctly.
I have a problem: when implementing this code on a local work site (I am an office plankton, yes) - the behavior is similar to the behavior on JSfiddle, nothing falls to the console, there is practically no programming experience, I don’t imagine how to even google it.
[UPDATE]: Yes, indeed, it is necessary for mice to hang the focus on the display window in jsFidle (lower right). I did not execute the code (there is a self-written extension for G.Chrome, which increases some functionality for the site in LAN at work) I don’t know why, but moving it to the very top of the extension file helped. I am grateful to those who answered, your answers prompted me to a decision :)
